To review the data with respect to prevalence and risk factors of metabolic syndrome (MetS) in bipolar disorder patients. Electronic searches were done in PUBMED, Google Scholar and Science direct. From 2004 to June 2011, 34 articles were found which reported on the prevalence of MetS. The sample size of these studies varied from 15 to 822 patients, and the rates of MetS vary widely from 16.7% to 67% across different studies. None of the sociodemographic variable has emerged as a consistent risk factor for MetS. Among the clinical variables longer duration of illness, bipolar disorder- I, with greater number of lifetime depressive and manic episodes, and with more severe and difficult-to-treat index affective episode, with depression at onset and during acute episodes, lower in severity of mania during the index episode, later age of onset at first manic episode, later age at first treatment for the first treatment for both phases, less healthy diet as rated by patients themselves, absence of physical activity and family history of diabetes mellitus have been reported as clinical risk factors of MetS. Data suggests that metabolic syndrome is fairly prevalent in bipolar disorder patients.

Cancer is a disease wherein abnormal cells divide without control and are able to attack other tissues. Most of the patients and their families face some degree of depression, anxiety, and fear when cancer becomes a part of their lives. They feel helpless and eager to find ways on how to get rid of it. The study focuses on anxiety among breast cancer patients. It aims at investigating cancer, its symptoms, and effects the disease has on the anxiety level of patients.

Background: Cyclic nucleotide Phosphodiesterases (PDEs) are ubiquitously distributed in mammalian tissues and play a major role in cell signaling by hydrolyzing cyclic Adenosine Monophosphate (cAMP) and cyclic Guanosine Monophosphate (cGMP). Impairments in signal transduction have been implicated as possible mechanism of reduced plasticity and neuronal survival in major depressive disorders. PDE inhibitors possess a potentially powerful means to manipulate secondary messengers involved in learning, memory and mood. Cilostazol is an antiplatelet agent indicated for the treatment of intermittent claudication with peripheral artery occlusion and for the prevention of ischemic stroke worldwide. Various animal studies have reported neuroprotective, anti apoptotic, cognition and cerebral blood flow improvement properties of cilostazol. Materials and Methods: In this study, the antidepressant and anxiolytic effects of cilostazol were evaluated in mice using behavioral tests sensitive to clinically effective antidepressant compound. Results: Cilostazol, administered intraperitoneally (20 mg/kg), decreased immobility time of mice when subjected to forced swim test and tail suspension test as compared to standard fluoxetine (20 mg/kg). Cilostazol also produced significant decrease in the number of marbles buried as compared to fluoxetine in marble burying model. Conclusion: The present study suggests that cilostazol possesses potential antidepressant and anxiolytic activity, which could be of therapeutic interest for use in patients with depressive disorders.

Context : Sleep deprivation is known to have detrimental effects on attentional resources and cognitive functions. Aim : The aim of this study is to assess the changes in performance, due to 24 h of sleep deprivation, in medical students Materials and Methods : The performance was assessed using simple paper-pencil tasks, such as digit symbol substitution test, digit vigilance test, and letter cancellation tasks. Results : The results revealed an increase in the number of errors in letter cancellation tasks and digit vigilance test, with a significant decrease in the number of correct responses on the letter cancellation task. The time taken to complete the tests increased with lack of sleep, with the digit symbol substitution test being affected the most. Discussion : This study infers that sleep deprivation for 24 h affected the judgment ability more than the response speed. Conclusion : Sleep deprivation might lead to compromised performance of medical students in examinations.

Context: Insula, which is a vital brain region for self-awareness, empathy, and sensory stimuli processing, is critically implicated in schizophrenia pathogenesis. Existing studies on insula volume abnormalities report inconsistent findings potentially due to the evaluation of 'antipsychotic-treated' schizophrenia patients as well as suboptimal methodology. Aim: To understand the role of insula in schizophrenia. Materials and Methods: In this first-time 3-T magnetic resonance imaging study, we examined antipsychotic-naive schizophrenic patients (N=30) and age-, sex-, handedness- and education-matched healthy controls (N=28). Positive and negative symptoms were scored with good interrater reliability (intraclass correlation coefficient (ICC)>0.9) by using the scales for negative and positive symptoms. Gray matter volume of insula and its anterior/posterior subregions were measured by using a three-dimensional, interactive, semiautomated software based on the valid method with good interrater reliability (ICC>0.85). Intracranial volume was automatically measured by using the FreeSurfer software. Results: Patients had significantly deficient gray matter volumes of left (F=33.4; P<0.00001) and right (F=11.9; P=0.001) insula after controlling for the effects of age, sex, and intracranial volume. Patients with predominantly negative symptoms had a significantly deficient right posterior insula volume than those with predominantly positive symptoms (F=6.3; P=0.02). Asymmetry index analysis revealed anterior insular asymmetry to be significantly reversed (right>left) in male patients in comparison with male controls (left>right) (t=2.7; P=0.01). Conclusions: Robust insular volume deficits in antipsychotic-naive schizophrenia support intrinsic role for insula in pathogenesis of this disorder. The first-time demonstration of a relationship between right posterior insular deficit and negative symptoms is in tune with the background neurobiological literature. Another novel observation of sex-specific anterior insular asymmetry reversal in patients supports evolutionary postulates of schizophrenia pathogenesis.

Background: Previous studies show that the prolonged use of dextromethorphan produces cognitive deterioration in humans. Aim: The aim of this study was to investigate the effect of a single dose of dextroemthrophan on psychomotor performance and working memory capacity. Materials and Methods: This is a randomized, double-blind, controlled, and prospective study. Thirty-six (17 women, 19 men) medical students enrolled in the study; half of them (7 women, 11 men) were given placebo, while the other half (10 women, 8 men) received dextromethorphan. The choice reaction time, critical flicker fusion threshold, and N-back working memory task were measured before and after 2 h of taking the drugs. Results: Dextromethorphan showed a significant deterioration in the 3-back working memory task (P<0.05). No significant changes were seen as regards the choice reaction time components (total, recognition, motor) and critical flicker fusion threshold (P>0.05). On the other hand, placebo showed no significant changes as regards the choice reaction time, critical flicker fusion threshold, and N-back working memory task (P>0.05). Conclusion: A single dose of dextromethorphan has no effect on attention and arousal but may significantly impair the working memory capacity.

Context: While some studies have found disparities between subtypes of irritable bowel syndrome (IBS), others did not found such differences. Aim: This study aimed to investigate whether there are differences in psychological features between the subtypes of IBS. Settings and Design: A cross-sectional study was performed on all consecutive outpatients IBS diagnosed (from Oct. 2010 to Oct. 2011) in Taleghani Hospital gastroenterology clinic, Tehran, Iran. Materials and Methods: A total of 153 consecutively diagnosed IBS patients (using Rome III criteria); including 80 constipation-predominant (IBS-C), 22 diarrhea-predominant (IBS-D), and 51 mixed IBS (IBS-M) were asked to complete the Symptom Checklist 90 Revised (SCL-90-R). Statistical Analysis: Pearson's chi-square test was used to compare nominal variables. One-way ANOVA was used to compare continuous variables. Results: Although IBS-C patients were more suffered from psychiatric disorders, there were no statistical differences between mean score of IBS-C, IBS-D, and IBS-M patients regarding to all of SCL-90-R subscales and three global indices including Global Severity Index (GSI), Positive Symptom Distress Index (PSDI) and Positive Symptom Total (PST) (P<0.05). Conclusion: Our finding showed that there are no different symptomatic profiles between IBS subtypes.

A lot of research has been directed on wellbeing and disability in many non-communicable disease conditions. In this context, health-related aspects of life and quality of life (QOL) are receiving a lot of focus. Many Quality of Health measures are available, of which World Health Organization Quality of Life (WHOQOL-BREF) is one of the most popular. Translating and adapting this tool is useful in view of research happening in a multicultural arena. Though translations into Hindi and other Indian languages including Tamil and Kannada have been done, a Malayalam version is not available. This paper discusses the steps adopted in this exercise and the challenges in translating WHOQOL-BREF to Malayalam from the original English version.

Background: Patients seek treatment for substance use disorders because of certain reasons that they consider significant and important, but on the other hand, they do have various fears or apprehensions about the treatment, which act as barriers for treatment-seeking. In this study, we aim to assess their reasons for seeking treatment, the associated fears about treatment, their social support and locus of control, and also to find the relationship among these variables. Materials and Methods: One hundred subjects attending the Drug Deaddiction and Treatment Center, Postgraduate Institute of Medical Education and Research (PGIMER) were prospectively recruited, with purposive sampling from 15 June to 14 July, 2011. The sociodemographic and clinical variables were ascertained through a semi-structured performa. The PGI Locus of Control Scale, Social Support Scale, and Reasons of Help-seeking and Fear Questionnaire were applied. Results: The common reasons for seeking treatment were - having become a habitual user, taking substance for a long time, and a need to take it every day. The common fears about treatment were the fear of disappointing others, loss of secrecy of substance use, and being considered a failure in life. The locus of control was primarily internal. Certain reasons like taking substance for a long time, feeling ill, and feeling sad were associated with a lower social support. Social support was not associated with the locus of control. The most affected areas of impairment were finance and health. Conclusions: Certain reasons and fears regarding treatment are more common than others. It is important to look into reasons and fears that are related to better treatment outcomes.

Background: There is a paucity of studies done on medically unexplained physical symptoms (MUPS) in Kerala, India. The objective of this study was to examine the sociodemographic and other clinical variables associated with this condition. Materials andMethods: The clinical sample was taken from the General Medicine Clinic of a tertiary care hospital, in Kerala. The referred cases meeting the criteria (N=48) for medically unexplained physical symptoms were enrolled for this cross-sectional study. The medical doctor with experience in psychiatry completed the questionnaire. Results: Most of the patients were middle-aged females from rural areas. The most common symptom reported was headache. Most of the patients had symptoms for five years or more and had seen two-to-five consultants. A majority of the patients had undergone special investigations and a few had expensive and invasive investigations. Cluster C personality disorders were the most common associated personality disorders with medically unexplained physical symptoms. Conclusions: To our knowledge this is the first psychosocioeconomic study on medically unexplained physical symptoms, done in Kerala, India. Medically unexplained physical symptoms cause loss of productivity and economic burden and are a major public health problem. Future studies are warranted focusing on non-pharmacological treatment, psycho-education on mind-body association, and medical models on specific cytokines associated with medically unexplained physical symptoms for personalized management, and to examine the effect of a combination of pharmacotherapy and cognitive behavioral therapy.

Background: Entorhinal cortex (ERC), a multimodal sensory relay station for the hippocampus, is critically involved in learning, emotion, and novelty detection. One of the pathogenetic mechanistic bases in schizophrenia is proposed to involve aberrant information processing in the ERC. Several studies have looked at cytoarchitectural and morphometric changes in the ERC, but results have been inconsistent possibly due to the potential confounding effects of antipsychotic treatment. Materials and Methods In this study, we have examined the entorhinal cortex volume in antipsychotic-naïve schizophrenia patients (n=40; M:F=22:18) in comparison with age, sex, and handedness, matched (as a group) with healthy subjects (n=42; M:F=25:17) using a valid method. 3-Tesla MR images with 1-mm sections were used and the data was analyzed using the SPSS software. Results: Female schizophrenia patients (1.25±0.22 mL) showed significant volume deficit in the right ERC in comparison with female healthy controls (1.45±0.34 mL) (F=4.9; P=0.03), after controlling for the potential confounding effects of intracranial volume. However, male patients did not differ from male controls. The left ERC volume did not differ between patients and controls. Conclusions: Consistent with the findings of a few earlier studies we found a reduction in the right ERC volume in patients. However, this was limited to women. Contextually, our study finding supports the role for ERC deficit in schizophrenia pathogenesis - perhaps mediated through aberrant novelty detection. Sex-differential observation of ERC volume deficit in schizophrenia needs further studies.

Context: Suicidal ideation in depressed patients is a serious and emergent condition that requires urgent intervention. Intravenous ketamine, an N-methyl-D-aspartate (NMDA) antagonist, has shown rapid antidepressant effects, making it a potentially attractive candidate for depressed patients with suicidal risk. Aims: In India few studies have corroborated such findings; the present study aimed to assess the effectiveness and sustainability of antisuicidal effects of ketamine in subjects with resistant depression. Settings and Design: Single-center, prospective, 4 weeks, open-label, single-arm pilot study. Materials and Methods: Twenty-seven subjects with DSM-IV major depression (treatment resistant) were recruited. The subjects were assessed on Scale for Suicidal Ideation (SSI), 17-item Hamilton Depression Rating Scale (HDRS). After a 2-week drug-free period, subjects were given a single intravenous infusion of ketamine hydrochloride (0.5 mg/kg) and were rated at baseline and at 40, 80, 120, and 230 minutes and 1 and 2 days postinfusion. Results: The ketamine infusion was effective in reducing the SSI and HDRS scores, the change remained significant from minute 40 to 230 at each time point. Conclusions: The real strength of this study rests in documenting the rapid albeit short-lasting effect of ketamine on suicidal ideation in depressed patients.

Context: Studies on acute psychosis in patients from India report good outcome. A small proportion of these patients may suffer relapses or other develop major psychiatric disorders later. Aim: The aim of this study was to examine the diagnostic stability of acute psychosis in patients from India. Materials and Methods: The records of patients who presented with the first episode of acute and transient psychotic disorder (n=57) over 1 year (2004) were analyzed, and the follow-up data at the end of 1 and 2 years were recorded. Results: The mean age of the sample was 30.72 years. The mean duration of illness episode was 18.15±17.10 days. The follow-up data were available for 77.2% (n=44) and 75.4% (n=43) of the sample at the end of first and second years. Relapse was recorded in 47.4 and 54.4% at the end of first and second years, respectively. Conclusion: The diagnosis changed into other disorders such as bipolar disorder, schizophrenia, and unspecified psychosis, while a majority retained the initial diagnosis of acute psychosis. The findings suggest that acute psychosis is a relatively stable condition. A small percentage of these patients may go on to develop schizophrenia or bipolar disorder.

Obsessive compulsive disorder (OCD) is commonly regarded as a disorder with good insight. However, it has now been recognized that insight varies in these patients. Pathological beliefs seem to lie on a continuum of insight, with full insight at one end and delusion at the other. This can indeed pose a considerable challenge, especially in a scenario where the phenomenon is difficult to discern. We report a case of OCD, which was initially diagnosed as psychosis.

Subdural hematoma is a rare but serious complication following electroconvulsive therapy (ECT), a frequently used treatment modality in the management of various psychiatric morbidities including bipolar affective disorder (BAD). There are very few reports of intracranial bleeding following ECT in the literature. A 38-year-old female, known case of BAD for last fifteen years receiving ECT, presented with the symptoms of dysphasia, headache, left sided paresis, and sudden deterioration of sensorium. Computed tomography (CT) scan of the brain was suggestive of left-sided fronto parietal chronic subdural hematoma with midline shift that was drained successfully.

Rubinstein-Taybi syndrome (RTS) is a rare genetic disorder with characteristic physical anomalies. It is characterized by mental retardation, postnatal growth deficiency, microcephaly, specific facial characteristics, broad thumbs, and big toes. Behavioral problems are common with RTS; they include mental retardation, impulsivity, distractibility, instability of mood, stereotypes, poor coordination, atypical depression, and mania. To date, there is lack of literature on the presence of schizophrenia or non-affective psychosis with RTS. Here, we describe two cases where there is co-morbid psychosis with RTS. One case is diagnosed as paranoid schizophrenia and the other as psychosis possibly schizophrenia. Genetic analysis was not done due to unavailability. The possible etiological factors for the association of psychosis with RTS are discussed. Factors such as regulators of RNA polymerase II and hypoxia-inducible factor 1 alpha (HIF1A) may be some common etiological factors for the association of schizophrenia or non-affective psychosis and RTS. Schizophrenia / non-affective psychosis can be a comorbid psychiatric condition with RTS.

Olanzapine is an atypical antipsychotic drug which is available in oral and injectable forms that is used for treatment of various psychiatric disorders. We report a rare case of tardive dystonia after receiving single dose of olanzapine (10 mg) in parental form. Clinicians should be very vigilant regarding this rare side effect with use of olanzapine in clinical practice.

Gender identity disorder is one of the most controversial diagnoses of DSM-IV and almost incomparable in the complexity of its social, ethical and political considerations to any other diagnosis. We present a case of 30 year-old male who presented with complaints of suggestive of depressive disorder with a recent suicidal attempt. Careful history taking reveals underlying conflicts with prominent gender dysphoria and social complexities. The patient is managed primarily by pharmacotherapy and harm reduction model. Our case reflects a unique coping strategy against the present sociocultural values and ambiguity of law in this part of the world.

The Rime of the Ancient Mariner was written by Coleridge and is a classic poetry about retribution, punishment, guilt, and curse. Religious beliefs and delusions can arise from neurologic lesions and anomalous experiences, suggesting that at least some religious beliefs can be pathological. Looking at the poem through the psychiatric and psychological domain, the symbolism, the narration and the entire setting of the poem represents Post Traumatic Stress Disorder. Mariner's reactions are beautifully portrayed from the psychoanalytic point of view and the literary piece shows claustrophobia, stygiophobia, dikephobia, and poinephobia. The mental stress of a person under a crisis situation has remarkably been evoked in this poem. This incredible piece of art expresses how the realization of divine love within oneself has the power to heal pain and suffer.
